Due to the simple structure of the sealing rings, the injection mold combination of the sealing rings generally consists of only an upper mold plate and a lower mold plate. The upper mold plate is provided with guide pins, and the lower mold plate is provided with guide holes that match the guide pins.

[0017] The above technical objectives of the present invention are achieved through the following technical solutions:

[0018] A method for implementing a disassembly and assembly mechanism, comprising the following disassembly steps: step 1.1, lifting the mold to the same height as the No. 1 plate body by a lifting vehicle, and moving the mold horizontally to the position of the No. 1 plate body; step 1.2, using an electromagnet to magnetically attract the template and pull it up to achieve demoulding, and transferring the template to the No. 2 plate body by an upper screw assembly; step 1.3, inflating the airbag assembly, and rotating the No. 3 plate body to vertical; step 1.4, rotating the No. 2 plate body to vertical, rotating the template to a vertical state and positioning it between the No. 2 plate body and the No. 3 plate body; step 1.5, exhausting the right airbag, and tilting the template toward the No. 3 plate body; step 1.6, the No. 3 plate body descends, so that the flipped template is located on the No. 3 plate body with the mold cavity facing upward, and then exhausting the left airbag, and then flipping the No. 2 plate body to the water Flat; including the following installation steps: step 2.1, inflate the airbag assembly after the action in step 1.6 is completed again; step 2.2, rotate the No. 2 plate to vertical first, and then rotate the No. 3 plate to vertical; step 2.3, exhaust the left airbag, first lay the No. 2 plate flat, and then lay the No. 3 plate flat; step 2.4, the electromagnet magnetically attracts the template on the No. 2 plate and transports it to the top of the No. 1 plate; step 2.5, the template on the No. 1 plate is adjusted longitudinally and transversely to achieve the upper and lower alignment of the two templates, and the vertical lifting rod is moved down to complete the mold closing.

[0019] In summary, the present invention has at least one of the following beneficial effects:

[0020] (1) The upper mold plate is lifted by magnetic suction to realize the mold opening and disassembly, and then the upper mold plate is turned over by the rotation of the second plate and the third plate; the opened mold can be closed by reversing the disassembly and assembly mechanism. Obviously, this design makes the mold disassembly and assembly easier and improves the safety performance of disassembly and assembly by using the assistance of mechanical structure;

[0021] The template will tilt and slide down when flipping, causing the lower edge of the template to collide with the frame, which can easily cause damage to the mold and the middle plate. The design uses an airbag assembly to cushion the bottom of the template during upward flipping with an inflated airbag assembly to reduce impact damage, and the deflated airbag assembly assists the template in flipping downward.

[0022] (2) The significance of the airbag assembly being divided into two parts, the left and right parts, is that the template will first rotate to a vertical position and then remain in the vertical position. For example, when the template needs to be flipped over to the No. 2 plate, the left airbag is exhausted, making the center of gravity of the template unstable and the template tends to tilt toward the No. 2 plate. The template and the No. 2 plate are tilted and fitted together. Because of the pre-fitting relationship, the impact between the template and the No. 2 plate is reduced when the No. 2 plate rotates downward, thereby reducing damage to the mold.

[0023] (3) The coordinated design of the guide rod and the spring makes it difficult for the electromagnet to cause impact damage to the upper surface of the template during the downward pressure process; and the diameter of the through hole is larger than the diameter of the guide rod, so that the electromagnet has the function of fine-tuning the tilt angle, which meets the following working conditions: when the surface of the No. 2 plate is damaged, the upper template is slightly tilted on the No. 2 plate. At this time, in order to effectively fit with the back of the upper template, the electromagnet also needs to adjust the tilt angle synchronously, so that the template on the No. 2 plate can be effectively fitted and magnetically attracted.

[0024] (4) When the lower screw assembly and the lower push rod are combined for assembly and lifting, the positions of the upper mold plate and the lower mold plate are aligned, which is conducive to more efficient mold assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0054] Embodiment 1, a disassembly and assembly mechanism of an injection mold, referring to Figure 1 , including a frame 1, the frame 1 is a metal frame;

[0055] The upper surface of the frame 1 is provided with a plate 21, a plate 22 and a plate 23 for placing the template; the plate 21, the plate 22 and the plate 23 are all rectangular steel plates, and the three plates are arranged flat in sequence along a straight line.

[0056] For the first plate 21, it is located on the left side of the frame 1. For the specific structure, refer to Figure 1 and Figure 2 ;

[0057] The frame 1 is provided with a lower screw assembly 81 for driving the first plate body 21 to move back and forth laterally.

[0058] The specific structure of the lower screw assembly 81 is as follows: a linear track for sliding is provided between the frame 1 and the first plate body 21, and a manual screw is installed between the frame 1 and the first plate body 21, the manual screw is rotatably connected to the frame 1, and a threaded sleeve for threaded connection with the screw is fixed below the first plate body 21, and a handle is installed at the end of the manual screw, and the employee rotates the handle to drive the first plate body 21 to move back and forth linearly on the frame 1;

[0059] The frame 1 is equipped with a lower push rod 82, which includes an oil cylinder and a piston rod. The cylinder body of the lower push rod 82 is fixed to the left side of the frame 1, and the rod body of the lower push rod 82 points to the central symmetry line of the first plate body 21, and the rod body of the lower push rod 82 is located above the first plate body 21;

[0060] The telescopic trajectory of the lower push rod 82 and the moving trajectory of the lower screw assembly 81 are arranged perpendicular to each other. The pushing direction of the lower push rod 82 is longitudinal, and the moving direction of the lower screw assembly 81 is transverse. The purpose is that when the mold is placed on the No. 1 plate 21, the specific position of the mold in the horizontal plane can be fine-tuned by operating the lower push rod 82 and the lower screw assembly 81, so that the two templates can be quickly aligned up and down when assembling the mold.

[0061] In order to facilitate smooth movement of the mold on the No. 1 plate 21, a plurality of raised slide bars 83 are provided on the upper surface of the No. 1 plate 21. The slide bars 83 are arranged in parallel, and the cross section of the slide bars 83 is an arc surface.

[0062] The function of the No. 1 plate 21 is to place the mold, and the lifting, separation and mold closing combined actions of the mold are completed on the No. 1 plate 21.

[0063] The mold of the first plate body 21 is transferred to the second plate body 22 by magnetic attraction. The specific structure is shown in FIG. Figure 1 and Figure 3-Figure 6 , an upper frame body is fixed to the upper end of the frame 1, and an upper screw rod assembly 33 is installed on the upper frame body;

[0064] The upper screw rod assembly 33 includes a slide plate that slides on the upper frame. The slide plate and the upper frame are connected by a slide rail, and the slide plate is installed with a threaded sleeve. The threaded sleeve is threadedly connected to the upper screw rod. The upper screw rod is rotatably connected to the upper frame. The upper screw rod is driven by a motor. Therefore, the upper screw rod assembly 33 realizes the back and forth movement of the slide plate on the upper frame through the forward and reverse rotation of the motor. The upper frame is provided with a remote control, which is used to control the forward and reverse rotation of the motor and stop the action.

[0065] The moving direction of the upper screw assembly 33 is longitudinal, which is in the same direction as the telescopic direction of the lower push rod 82;

[0066] Reference Figure 1 Since the No. 1 plate body 21, the No. 2 plate body 22 and the No. 3 plate body 23 are arranged in sequence along the moving direction of the upper screw assembly 33, it can complete the action of lifting the template of the No. 1 plate body 21 back and forth between the No. 2 plate body 22 or the No. 3 plate body 23.

[0067] The slide plate of the upper screw assembly 33 is installed with a vertical lifting rod 32, which includes a cylinder and a vertical piston rod; an electromagnet 31 is fixed to the lower end of the vertical lifting rod 32, and a vertical guide rod is provided between the two, so that the vertical lifting rod 32 can drive the electromagnet 31 to move up and down; the electromagnet 31 controls the magnetic suction action through a remote control.

[0068] Obviously, the template is magnetically attracted by the electromagnet 31, and then adjusted in height by the vertical lifting rod 32, and then adjusted in longitudinal position by the upper screw assembly 33, so as to complete the lifting and loading and unloading of the magnetically attracted template.

[0069] A buffer assembly is provided between the vertical lifting rod 32 and the electromagnet 31, and the specific connection structure is as follows:

[0070] Reference Figure 1 and Figure 3 The buffer assembly includes an upper plate 41 fixed to the vertical lifting rod 32, and a lower plate 42 fixed to the electromagnet 31; there is a gap between the upper plate 41 and the lower plate 42, and both are steel plates.

[0071] There are four vertical guide rods 43 sliding between the upper plate 41 and the lower plate 42. The guide rods 43 are provided with springs 44 that abut against the upper plate 41 and the lower plate 42. An upper pull block 45 is fixed to the upper end of the guide rod 43, and the upper pull block 45 abuts against the upper surface of the upper plate 41. A lower pull block 46 is fixed to the lower end of the guide rod 43, and the lower pull block 46 abuts against the lower surface of the lower plate 42. The upper pull block 45 and the lower pull block 46 are nuts threadedly connected to the guide rod 43.

[0072] Therefore, the elastic suspension connection between the upper plate 41 and the lower plate 42 enables the electromagnet 31 to be suspended below the vertical lifting rod 32 .

[0073] The main body of the electromagnet 31 is cylindrical, with the flat magnetic surface facing downward;

[0074] When the mold is magnetically attracted, when the electromagnet 31 moves downward, when the magnetic attraction surface of the electromagnet 31 is pressed against the mold surface, the lower plate 42 moves upward along the guide rod 43 to prevent the electromagnet 31 from excessively hitting the mold surface;

[0075] When the magnet iron rises, the lower plate 42 moves downward rapidly under the driving force of gravity and the compression spring 44 until the lower plate 42 abuts against the pull-down block 46 .

[0076] The spring 44 has a pressing effect on the upper plate 41, so that the magnetic surface and the surface of the mold can fit more closely.

[0077] When the second plate body 22 has potholes on its surface after long-term use, the placed template is prone to slightly tilt;

[0078] However, the electromagnet 31 only moves vertically, and it may be difficult for the magnetic surface of the electromagnet 31 to effectively fit with the surface of the template. Therefore, the following improved design is carried out, and the specific reference is made to the accompanying drawings. Figure 4 and Figure 5 :

[0079] The upper pull block 45 and the lower pull block 46 are both provided with a through hole 47 for the guide rod 43 to pass through. The diameter of the through hole 47 is 2 mm larger than the diameter of the guide rod 43. This design leaves a tilting space for the guide rod 43, so that the guide rod 43 can be slightly tilted in the through hole 47.

[0080] Obviously, under the downward drive of the spring 44, the electromagnet 31 can be slightly tilted within the tilted space to achieve the electromagnet 31 fitting the template; when the template is lifted, the template will automatically resume the vertical lifting action due to gravity.

[0081] After the mold template is hoisted to the second plate body 22, it is turned over.

[0082] The flip structure is as follows:

[0083] Reference Figure 1 , an intermediate plate 51 is provided on the upper surface of the frame 1, the intermediate plate 51 is a long rectangular metal plate, and the intermediate plate 51 is fixed to the frame 1;

[0084] Reference Figure 7 The second plate body 22 and the third plate body 23 are symmetrically hinged on both sides of the middle plate 51;

[0085] The frame 1 is provided with a push rod 52 for driving the second plate body 22 and the third plate body 23 to rotate vertically so as to realize the flipping of the template between the first plate body 21 and the second plate body 22.

[0086] The push rod 52 includes a cylinder and a rod body. The cylinder bodies of the two push rods 52 are hinged to the frame 1, the rod body of one push rod 52 is hinged to the lower surface of the second plate body 22, and the rod body of the other push rod 52 is hinged to the lower surface of the third plate body 23. The two push rods 52 are also symmetrically arranged relative to the middle plate 51.

[0087] The second plate body 22 and the third plate body 23 are both rotatably connected via a rotating shaft and the middle plate 51 .

[0088] Driven by the push rod 52, the second plate body 22 and the third plate body 23 switch positions between vertical and horizontal, and the rotation angle range is 0-90 degrees. The maximum rotation angle can be controlled by the stroke of the push rod 52;

[0089] The width of the middle plate 51 is 1 mm greater than the thickness of the flip template; the middle plate 51 is provided with an airbag assembly 7 that receives the lower edge of the flip template.

[0090] Reference Figure 7 and Fig.10 The frame 1 is provided with a control switch 6 for inflating and deflation of the airbag assembly 7, and the control switch 6 controls the inflation and deflation of the airbag.

[0091] The airbag assembly 7 includes a long strip of airbags, which are located on the upper surface of the middle plate 51. The airbags are inflated so that the lower edge of the flipped template can contact the airbags to act as a buffer. The airbags are used instead of raised rubber pads because the edge of the template will be pressed on the airbags when the template is flipped. At this time, the mold plate area can be flattened by deflating, which facilitates the magnetic lifting of the magnetic mold plate.

[0092] The upper surface of the middle plate 51 is provided with a groove for accommodating the airbag. After the airbag is deflated, the wall thickness of the airbag and the depth of the groove are the same, so that the template pressed on the airbag is more flat.

[0093] The specific structure of the airbag assembly 7 is shown in FIG. Figure 8-Figure 10 The airbag assembly 7 includes two left airbags 71 and right airbags 72 of the same structure, and the left airbag 71 and the right airbag 72 are arranged along the length direction of the middle plate 51.

[0094] The left airbag 71 is arranged toward the second plate body 22, and the right airbag 72 is arranged toward the third plate body 23; the control switch 6 includes a button member 61 for controlling the independent exhaust of the left airbag 71 and the right airbag 72, the button member 61 controls the valve body switch of the exhaust pipe, and the control switch 6 also includes an inflation button 62;

[0095] The employee turns on the inflation button 62, and the air pump on the rack 1 inflates the two left airbags 71 and the right airbag 72 at the same time, and a one-way valve is used to allow the inflation tube to only take in air;

[0096] When the template flips downward, the button 61 is first used to vent the airbag near the flipping position, so that the template is tilted to fit the flipped plate. As the flipped plate rotates downward, the template slowly rotates downward. When the flipped plate is horizontal, the button 61 is controlled to vent the other airbag.

[0097] Embodiment 2, a disassembly and assembly mechanism of an injection mold, which is different from Embodiment 1, referring to Fig.11 , a plurality of protrusions are fixedly extended on both sides of the middle plate 51, and a rotating shaft 93 is fixed to the protrusions, and the rotating shaft 93 and the middle plate 51 are kept fixed;

[0098] There are multiple sleeves on the rotating shaft 93, and a retaining spring is installed at the sleeve and the rotating shaft 93 to prevent the sleeve and the rotating shaft 93 from moving linearly relative to each other, and the sleeve at this location is fixed to the corresponding second plate body 22 and the third plate body 23, so the second plate body 22 and the third plate body 23 can rotate vertically around the rotating shaft 93 close to each other;

[0099] The sides of the second plate body 22 and the third plate body 23 are provided with a rotating shaft 94 that can rotate.

[0100] The specific structure is that a shaft sleeve is also fixed on the side of the second plate body 22, and the rotating shaft 94 is passed through the shaft sleeve to realize rotation, and a retaining spring is also used to limit the linear movement of the rotating shaft 94;

[0101] For the second plate body 22, the corresponding rotating shaft 93 and the rotating shaft 94 are vertically arranged, and a coaxial crown tooth 910 is fixed at the end of the rotating shaft 93, and a coaxial shaft tooth 911 is fixed at the end of the rotating shaft 94, and the shaft tooth 911 is meshed with the crown tooth 910 to realize gear linkage;

[0102] Therefore, when the second plate body 22 rotates vertically around the corresponding rotating shaft 93, the rotating shaft 94 also rotates vertically around the rotating shaft 93, and because of the meshing relationship between the shaft teeth 911 and the crown teeth 910, since the crown teeth 910 are relatively stationary, and the crown teeth 910 and the rotating shaft 93 are coaxially arranged, the shaft teeth 911 mesh and rotate around the crown teeth 910, so the shaft teeth 911 rotate along the tooth openings of the crown teeth 910, and the rotation of the shaft teeth 911 realizes the self-rotation of the rotating shaft 94 around its own axis.

[0103] A side baffle 95 is fixed to the rotating shaft 94 on the second plate, and the side baffle 95 rotates synchronously with the rotating shaft 94 .

[0104] When the second plate body 22 is horizontal, the side baffle 95 is located below the upper surface of the second plate body 22, and the side baffle 95 is in a horizontal arrangement;

[0105] Reference Fig.12 When the second plate body 22 is vertical, the side baffle 95 vertically protrudes from the second plate body 22 to form a lateral baffle;

[0106] Reference Fig.11 The connection relationship between the rotating shaft 93 , the rotating shaft 94 , the crown teeth 910 and the shaft teeth 911 corresponding to the third plate body 23 and the middle plate 51 is the same as the connection structure between the second plate body 22 and the middle plate 51 .

[0107] Reference Fig.12 The side baffles 95 provided on the rotating shaft 94 on the third plate body 23 and the side baffles 95 on the second plate body 22 are staggered in position. When the second plate body 22 and the third plate body 23 are vertical at the same time, the side baffles 95 on the two plate bodies are interlaced.

[0108] The working effect is:

[0109] The gear linkage realizes the rotation of the side baffle 95, and the oil cylinder is used as the power source for rotation in this solution. Therefore, the blocking force of the side baffle 95 is relatively large, and the blocking stability is relatively excellent. The template is not easy to slide out from the second plate body 22 and the third plate body 23 during the flipping process. In addition, the blocking effect of the side baffle 95 also avoids the situation where employees mistakenly insert their hands into the two plates and are clamped, thereby improving safety performance.

[0110] The side baffle 95 needs to be rotated, and its purpose is to refer to Fig.11 and Fig.13 After some molds are split, they need to be cleaned. In this case, the lifting frame 96 is needed to move the upper template 101 at the position of the third plate 23 to the lifting frame 96 platform of the same height. At this time, the third plate 23 is in a horizontal position, and the side baffle 95 needs to be located below the upper surface of the third plate 23, so as not to block the upper template 101 from being pushed onto the lifting frame 96.
